It was developed by Turbine Entertainment Software and published by Microsoft. Players must buy the game software and pay a monthly fee to play. AC is considered one of the most successful MMORPGs, but due to lack of exposure never reached the heights of EverQuest or Ultima Online even despite not increasing its monthly fee over the years (it has always cost $9.95 USD per month). One expansion, Dark Majesty, was released in 2001. A second expansion is under very careful consideration, as this game is quite old and some feel it needs a graphics upgrade. Asheron's Call 2: Fallen Kings was released on November 22, 2002. Both the original and the sequel feature free monthly updates or "patches" that introduce new features and gameplay improvments.
